FIREPROOF BUILDING.

SPECIFICATION formingpart of Letters Patent No. 593,804, dated November16, 1897.

Application filed M8011 3 9 To all whom it may concern:

Be itknown that I, JULIUS E. HINTZE, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Fireproof Buildings, ofwhich the following is a specification.

My invention relates to fireproof buildings, and has for its object theproduction of an economical and efficient construction for the floors,ceilings, and partitions of ordinary wooden-beam structures.

My invention consists of means for renderin g wooden structuresfireproof and comprises a fireproof sheathing placed above and below thefloor-joists and securedthereto by longitudinal fireproof strips, aflooring attached to the top strips, and a fireproof ceiling secured tothe fireproof bottom strips.

My invention consists, further, of detailso constructionhereinafterdescribed,and pointed out in the claims.

The accompanying drawing, which forms a part of my specification,represents a sectional perspective view of the floor and ceiling of myimproved fireproof wood structure.

Referring to the drawing, B B represent the ordinary wooden floor beamsor joists of a building. These beams are covered above and below bysheathing or a layer of fireproof material a, preferably asbestos paper.This asbestos sheathing extends over the floorspace above and below saidfloor beams- Fireproof strips 17 b, which are cut from thick asbestospasteboard, are nailed longitudinally along the beams above and belowand serve to secure the said sheathing to the beams. An ordinaryflooring f, constructed of the usual floor-planks, is supported on thestrips 1), thus leaving an open space between the said flooring and thesheathing. To the lower strips 1) are attached sheet-metal lathing 0,and a suitable plaster dis laid therein, forming an ordinary ceiling.The metal lathing may be replaced by a sheathing of wiregauze, which maybe nailed to the asbestos strips b, and covered with suitable plaster,Thin metal sheets may also be substituted for the lathing or gauze orterra-cotta or other fireproof plates or slabs Serial No. 628,155. (Nomodel.)

be used in place of the lathing and plaster. An open space is alsoprovided between the sheathing and the metal lathing by the strips 1).

It is obvious that the above-described structure can be applied to thepartitions and walls as well as to the floors of a building, thusrendering the entire building fireproof.

My improved means for rendering structures'fireproof may be applied tobuildings already completed as wellas to those in the course oferection, it being only necessary in the former case to remove the oldflooring and ceiling. It will be noted from the above description thatthe floor beams or joists are protected on both sides by the fireproofsheathing. The open spaces above and below said joists act as anadditional protection.

. Having thus described my invention, I claim as new and desire tosecure by Letters Patent v 1. In a fireproof structure, the combination,with the wooden floor-joists, of a fireproof sheathing attached to theupper and lower sides thereof, andlongitudinal fireproof strips securedto the upper and lower sides of said joists and serving as a means bywhich the floor and ceiling are attached to said joists, substantiallyas set forth.

2. In a fireproof structure, the combination with the floor-beams of afireproof sheathing applied to the upper and lower sides thereof,fireproof strips extending longitudinally along the upper and lowersurfaces of said floor-beams, a flooring secured to the upper strips, afireproof ceiling secured to the lower strips and air-spaces formedabove and below said floor-beams, substantially as set forth.

3. In a fireproof structure,the combination, with the woodenfloor-joists, of an asbestos sheathing attached to the upper and lowersides thereof, longitudinal asbestos strips secured to the upper andlower sides of said joists, a flooring attached to the upper strips, andmetal lathing secured to the lower strips and adapted to receive aplaster, substantially as set forth.

4. In a fireproof structure,the combination, with the floor-beams, of afireproof sheathing applied to the lower side of said floormy inventionI have signed my name in presenee of two subscribing Witnesses.

JULIUS E. IIINTZE.
